attempting to match the submission requirements, I'm using OVRPlatformMenu.cs to show the dialog when user presses the back button in the top menu. Unfortunately, although I'm able to confirm that OVRPlugin.ShowUI (OVRPlugin.PlatformUI.ConfirmQuit) is executed and the appropriate messages are logged, no ConfirmQuit-Dialog appears.
Did I forget any settings or is there a problem with my approach?
If this helps, debug log contains "[PlatformUI-ConfirmQuit] Showing @ 82.24489" (only once as expected) and public OVRP_1_1_0.ovrp_ShowSystemUI is called.
